Italso includes means for retaining the air in the airchamber While underpressu-re.

The invention further comprises. the combination and arrangement I of parts and construction of. details hereinafter, de scribed, shown in theaccompanying, draw: ings and; specifically pointed 011175 in, the claims.

In the accompanying drawings Eigure 1 is a vertical transverse'section of thenla vatory, basin; and automatically acting waste appliance, andseal and trap Fig.2, s an enlarged section of. the waste appliance showing the connections with the waste pipe and air chamber and sealing cup.

In, these views A is the basin, B is the outlet nozzle leading therefrom which discharges, into a sealing cup C communicating by means, of the outlet pipe D with the trap E which discharges into the sewer connections (not shown).

F is a plug which closes the opening leading from thesealing. cup G into the outlet pipe D. This plug is raised manually to drainthe basin and to admit air after each operation and .permitithe waste to flow into the trap E by means, of a hand pull J, rod K, and rock arm LI and rod M connected withlthe plug F. The operating means for the valve includingthe rod K, rock arm L and rod M, are always submerged in the trap, E andhence the air chamber G is always perfectly' .air tight until waste is dischargedor fresh air is admitted after each operation.

At, G is shown an air' chamber the walls of which inclose thesealing cup and outlet opening leading from thebasin A. Openings H, H, in the pipe D permit the waste Water to HOW, out of the air chamber when the air pressure is overcome. The level of the waste fluid remaining in the trap E should preferably be high enough to cover the openings H, H, in the outlet pipe and preserve the air in the air chamber until the pressure is overcome by the weight of waste fluid in the. basin.

The operation of the device is, as follows: The, manual operation when it is desired to empty the basin is simple and has already beendescribed to consist merely in lifting the plug by means of the hand lift. The automatic, action takes place when the user doesnot lift the plug but permits the waste water to accumulate in the basin, then the water flows" into the sealing cup and overflows into. the air chamber. The'seal of the cup prevents the escape, of the air meanwhile until the waste fluid has, attained a predetermined level in the basin, then the weight of the fluid will overcome the pressure of the air confined in the air chamber and also the weight of the fluid in the trap and will escape through the'openings H, H, in;the outlet pipe. The fluid in the trap will always prevent the escape of sewer gas into the basin and the seal formed in the cup and the outlet nozzle from the basin will prevent the upward escape of the air from the air chamber when under pressure.

It is obvious that the waste can be discharged wholly by means of the automatic air pressure controlled method, but a manual control is added to insure complete drainage of the sealing cup.

The outlet tube D leading from the cup is smaller in diameter than the diameter of the trap, and is preferably attached thereto by means of a screw thread so as to be adjustable therein. The cup is raised above the bottom of the chamber G and the level of the water in the basin is controlled by means of the level of the upper edge of the cup. In adjusting the cup the openings H, H, must not be covered up.

Having described the invention what I claim as new and desire to secure by Letters Patent is:

1. The combination with a basin having an outlet nozzle, of means for automatically controlling the discharge of fluid from said basin, said means comprising an air confining chamber arranged to receive said outlet nozzle and communicating with the exterior atmosphere only by way of said nozzle, said chamber having a valveless drainage outlet near the bottom thereof, a waste pipe connected with said drainage outlet, said waste pipe being provided with a liquid seal, a sealing cup within said air chamber and arranged to receive the. basin outlet nozzle, the wall of said sealing cup extending above the drainage outlet of the air chamber and'having the rim thereof spaced from the top of said air chamber and manually operated means for draining said sealing cup.

2. The combination with a basin having an outlet nozzle of means for automatically controlling the discharge of fluid from said basin, said means comprising an air confining chamber arranged to receive said out let nozzle and communicating with the exterior atmosphere only by way of said nozzle, said chamber having a valveless drainage outlet near the bottom thereof, a Waste pipe connected with said drainage outlet, said waste pipe being provided with a liquid seal, a sealing cup within said air chamber and arranged to receive the basin outlet nozzle, the wall of said sealing cup extending above the drainage outlet of the air chamber and having the rim thereof spaced from the top of said air chamber, said sealing cup being provided with a drainage outlet in its bottom, a plug for closing said drainage outlet and manually operated means for shifting said plug.

3. The combination with a basin having an outlet nozzle, of means for automatically discharging fluid accumulated in said basin, said means comprising an air confining chamber arranged to receive the outlet nozzle, said chamber communicating with the exterior atmosphere only by way of said nozzle, said chamber having a drainage outlet, a waste pipe connected with said drainage outlet, said waste pipe being provided with a liquid seal, and vertically adjustable means for sealing said air chamber for preventing the escape of air therefrom by way of the basin outlet, said adjustable sealing means comprising a cuparranged to receive the lower portion of the basin outlet, said cup having a drainage opening connected with the drainage opening from said air chamber, and a valve arranged to close said opening and manually operated means for opening and closing said valve.

4. The combination with a basin having an outlet, of means for automatically dischargingfluid accumulated in said basin, comprising, an air confining chamber, an outlet nozzle, extending from the outlet of the basin into said chamber, a sealing cup in said chamber and arranged to receive the end of the outer nozzle, said cup raised above the bottom of said air confining chamber, an outlet pipe supporting said cup upon the bottom wall of said chamber and provided with perforations intermediate of said cup and bottom wall of said chamber, a valve in said. outlet pipe, controlling the opening leading to said outlet pipe, an exterior trap communicating with said outlet pipe, and means for operating said valve, said means submerged within said trap.

5. The combination with a basin having an outlet, of means for automatically discharging fluid accumulated in said basin, including, an airconfining chamber communicating with said outlet from said basin, said air confining chamber having a separate outlet and vertically adjustable means for sealing said air chamber to prevent the escape of air therefrom by way of the basin outlet, said adjustable sealing means controlling the attainable Water level'in said basin.

6. The combination with a basin having an outlet nozzle, of means for automatically controlling the discharge of fluid from said basin, said means comprising an air con fining chamber arranged to receive said outlet nozzle and communicating with the exterior atmosphere only by Way of said nozzle, said chamber having a valveless drainage outlet near the bottom thereof, a waste pipe connected with said drainage outlet, said waste pipe being provided with a liquid seal, a sealing cup within said air chamber and arranged to receive the basin outlet nozzle, the'wall'of the sealing cup extending above the drainage outlet of the air chamsaid means at a point below the normal level 10 her and having the rim thereof spaced from of the liquid seal in said waste pipe.
